Biomechanical studies show increased anterior and rotational stability with double-bundle (DB) compared to single-bundle (SB) anterior cruciate ligament (ACL) reconstruction. The aim of this study was to evaluate the clinical results of four-tunnel DB ACL reconstruction.Seventy patients undergoing arthroscopic hamstring ACL reconstruction were prospectively randomized to DB (n = 35) or SB (n = 35) groups. Each bundle fixation was by means of a femoral EndoButton CL and a tibial biodegradable interference screw. Demographic data were comparable between groups, and the average age of all patients was 29 years. The average follow-up was 19 months for both groups and included a history, clinical evaluation with knee scores, and radiographs.The subjective results were similar in groups. The subjective International Knee Documentation Committee (IKDC) 2000 score was 88 P for DB versus 90 P for SB; the Lysholm score was 90 P for DB versus 93 P for SB; and the Cincinnati knee score was 91 P for DB versus 92 P for SB. The objective IKDC was significantly higher for DB: 78
